Patented Mar. 31, 1953 v UNITED STATES PATENT OFFICE- COVER Herbert W. Hempel, Belleville, Ill., assignor to Marsh Stencil Machine Company, Belleville, 111., a corporation of Illinois Application May 31, 1949, Serial No. 96,320

1 Claim. (Cl. 206-151) The present invention relates generally to closure devices, and more particularly to a cap for a brush or the like which is formed to facilitate the capture of all of the bristles without damage to them. r

In summary, the present invention comprises a cylindrical cap open at one end which includes a notch or bristle entry gap of selected form and depth in the wall opening into the mouth. As is more particularly shown in the drawing and described in the following specification, the boundary walls of the notch may be in the normal plane of the cap or they may be formed inset or outset as desired. In applying the cap to cover the bristles of a brush, the cap is rotated as it is installed in order to pass the bristles into the notch which deflects them into the interior of the cap. A modified construction contemplates a projecting tongue.

It is desirable to cap the bristles of many types of brushes, particularly those used sporadically during a work operation or used from time to time. One example is the fountain brush used to soap pipe joints to detect leaks, the capping of such preventing soapy liquid from getting on f" the support on which the brush is placed while not being used, such as the tool box or workers pocket. Another example is the stencil marking fountain brush when used with ink which cakes or hardens on the bristles if the brush is left uncleaned and in the open air. A substantially sealing cap disposed over such coated bristles prevents caking. However, standard caps are awkward to? apply, and damage the brushes through clipping ofi stray bristles each time they are applied.

Therefore, an object of the present invention is to provide a novel cap for bristle brushes and the like which includes a notch, tongue, or the like, for facilitating the trapping of the bristles of the brush without damage to them.

Another object is to provide a novel cap for bristle brushes or the like which is of cylindrical or other forms, open at one end, and which is cut away, extended or otherwise formed at one portion of the free edge to provide a trap or deflector for bristles when the cap or brush is rotated one relative to the other in the bristle encasing operation.

Another object is to provide a novel method of entrapping the bristles of a brush in a snugly fitting cap so that no damage is caused the bristles during the encasing operation.

Another object is to provide a novel cap construction incorporating a notch in the side which receives stray-bristles during an encasing 'action, and which, in the relative rotation of the cap and brush, lead the stray bristles into the interior of the cap without damage to them.

Other objects are to provide a novel cap for bristle brushes which is inexpensive, which may be quickly applied to the bristles of a brush, and which adequately covers the bristles of a brush to prevent contact thereof with the surface upon which the brush may be disposed and to 'substanportion shown in Fig. 1;

Fig. 11 is an end view thereof.

Referring to the drawing more particularly by reference numerals, and specifically considering Figs. 1 through 4, l0 indicate-s generally a cap formed in accordance with the teachings of the present invention. The cap I0 is of cylindrical construction including a cylindrical body l2, 9. closed end l4, and an open end It. A V- shaped notch I8 is formed in the body l2 inwardly of the open end It. Spaced indentations 20 may be provided for a purpose specified below. A fountain brush 22 is shown in association with the cap Ill and includes a handle 24 having a shoulder portion 26 which supports bristles 28.

In Figs. 1 and 2, the cap [0 and the brush 22 are shown in a preferred relationship preparatory to trapping the bristles 26 in the cap it. The bristles 28 are disposed in the notch 16, and either the brush 22 or the cap I rotated relative to the other in either direction. When expertly done, the bristles 23 will be fully entrapped within less than a rotation of either the brush 22 or the cap it. Even a novice can quickly entrap the bristles 28. While a preferred method of entrapping the bristles 28 is illustrated in Figs. 1 and 2, the cap l0 and brush 22 may be moved toward each other on the same axis, and, after a portion of the bristles have entered the cap i0, either the cap 19 or the brush 22 may be rotated relative to the other, whereupon the bristles 28 will be fully entrapped without damage.

In Figs. and 6 is shown a modification of the cap [6 in the form of a cap 39, The cap 30 is similar to the cap It with the exception of the shape of a notch- 32. The notch, 32 has one wall 34 deflected inwardly and a second wall 36 defiected outwardly as is clearly shown in Fig. 6. The form of notch 32 ofthe cap 30 facilitates bristle trapping, since the outwardly deflected wall, 35 serves to more positively trap stray bristles than the corresponding wall of the notch |8cf the cap H3.

In Figs. '7 through 9, there is shown a cap 49 which comprises a further modification of the present invention as initially disclosed in Figs. 1 through 4. The cap 40 includes a notch &2 of shallow depth which is defined by inwardly directed wall portions 44 and a bottom wall portion 46. The cap 39 is shown in association with a fountain stencil brush 48 which includes a hollow handle 59, a bevelled flange 52,, and bristles 5,4. As is clear from Fig. 9, the cap to is bevelled at its open end in correspondence to the bevelled flange 52.

In Figs. and 11 is shown a still further modification of the present invention. A cap 69 including a closed end 62 and an open end 64 has a projecting tongue 66 riveted or welded to or formed integral with the cap wall at the open end 64. The tongue 66 includes a bevelled edge 68v which will, deflect bristles into the cap. 60.

Manifestly, the method of entrapping the bristles of a brush is the same with the caps I0, 30, so, and 60. The particular cap is rotated relative to the brush, or vice versa, which insures rapid entrapping of the bristles without damage.

It. is manifest that the notch in the particular cap may be formed. of any desired. configuration, 50

such as a half V selected, to trap bristles in clockwise or counterclockwise rotation, and may have the defining walls distorted or not, as desired.

It is clear that there have been provided a novel cap construction and a novel method of applying a cap to the entrapment of bristles which fulfill the objects and advantages sought therefor;

iIt is to be understood that the foregoing description and the accompanying drawing have been given by way of illustration and example. "It is also to be understood that changes in form of the several parts, substitution of equivalent elements or steps, and rearrangement of parts or'steps; which will be readily apparent to one skilled in the art, are contemplated as within the scope of the present invention, which is limited only by the claim which follows.

What is claimed is:

In a brush assembly: a brush having a handle with bristles extending outwardly therefrom, the handle having a cylindrical shoulder portion extending axially from the bristle end thereof a predetermined distance, a cap. comprising an elongated tubular body closedat one end and open at the other end for receiving both the bristles and the cylindrical shoulder of said brush, said body having a bristle entrapping notch extending from said open end only partiallythe length, of the body, said notch being approximately equal in length tothe length of the cylindrical shoulder portion of the brush handle, and the body of the cap adjacent said notch being of, a diameter to fit sungly over the cylindrical shoulder portion, whereby the. bristles may be disposed the notch and twisted into the cap, and then may be substantially enclosed within the'cap when it is disposed upon the cylindrical shoulder portion.
